《百分数的意义》一节属于概念教学,通过本课例的研究,意在整合两种版本这一内容的编写意图,根据儿童智力活动形成的规律进行概念教学,探究小学生数学概括能力的培养的策略。如何培养这一能力?引导学生经历观察、体验、比较、分析的数学活动过程,并在这一活动过程中深刻把握百分数的实质,发展学生提出问题和研究问题的能力,培养概括能力,使学生真切积累数学概念学习的基本经验和方法。
Through the research of this lesson, this article intends to integrate the compilation intention of the two versions, to carry out the concept teaching according to the law formed by the children’s intellectual activities, and to explore the cultivation of the generalized abilities of the students in mathematics Strategy. How to cultivate this ability? To guide students through the process of observation, experience, comparison, analysis of mathematical activities, and in the process of grasping the essence of the percentage, the development of students’ ability to ask questions and research problems, develop general ability to enable students Really accumulate the basic concepts and methods of mathematical learning.
